BATTRI is a graphical Matlab interface to the C language two-dimensional quality grid generator Triangle developed by Jonathan Richard Shewchuk (email@example.com). BATTRI does the mesh editing, bathymetry incorporation and interpolation, provides the grid generation and refinement properties, prepares the input file to Triangle and visualizes and saves the created grid. Triangle is called within BATTRI to generate and refine the actual grid using the constraints set forth by BATTRI. BATTRI and Triangle are known to work on a number of platforms, including SGI's, SUN's, Pentium PC's under Linux (2.2.x and 2.4.x kernels), and Pentium PC's working under Windows. This version of BATTRI is known to work under both Matlab R11 and R12.
